We look at the division of 339917 by 23 
Let's see how many times 23 fits into 339917.

Moving on to step 1:
When dividing 3 by 23, we get 0 with a remainder of 3.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 3, we end up with 3.
Bring next digit (3) of the dividend behind the 3 and repeat the process: 33 / 23

Let's proceed to step 2:
If we divide 33 by 23, we get 1 and a remainder of 10.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
If we subtract 23 from 33, we get 10.
Take the next digit (9) from the dividend and append it to 10, then repeat: 109 / 23

Step 3:
If we divide 109 by 23, we get 4 and a remainder of 17.
The number 4 becomes the next digit in our result. 
Result so far: 14.0
The remainder is 17 after subtracting 92 from 109.
Grab the next digit (9) from the dividend, add it to 17, then carry on: 179 / 23

Step 4:
23 goes into 179 7 times with a remainder of 18.
Record the quotient 7 as the next digit in the result. 
Result so far: 147.0
If we take 161 away from 179, we end up with 18.
Take the next digit (1) from the dividend and append it to 18, then repeat: 181 / 23

Step 5:
If we divide 181 by 23, we get 7 and a remainder of 20.
Write down 7 as next digit of the result. 
Result so far: 1477.0
If we subtract 161 from 181, we get 20.
Take the next digit (7) from the dividend and append it to 20, then repeat: 207 / 23

Going ahead to step 6:
When dividing 207 by 23, we get 9 with a remainder of 0.
Write down 9 as next digit of the result. 
Result so far: 14779.0
Deduct 207 from 207 and we're left with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Moving on to step 7:
If we divide 0 by 23, we get 0 and a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 14779.0
If we take 0 away from 0, we end up with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Going ahead to step 8:
0 divided by 23 is 0 with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 14779.0
If we subtract 0 from 0, we get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

The final result is 14779.0 with a remainder of 0.0.
